Hashimoto’s Thyroiditis And Hair Loss: Everything You Need To Know

Levothyroxine & Hair Loss – 3 CAUSES HOW TO STOP IT

According to the U.S. National Library of Medicine, 1% to 2% of the U.S. population has Hashimotoâs thyroiditis. It occurs more often in women than in men and is the most common cause of underactive thyroid, also known as hypothyroidism, in the U.S. Hair loss is, for many, one of the most distressing symptoms of thyroid disorders and may be challenging to treat if you have Hashimotoâs thyroiditis.

Hair Loss As A Symptom Of Thyroid Problems

Growing hair is more complex than you think. Your blood vessels, skin cells, and oil glands are all responsible for strong and healthy hair. However, when your hormone production is disrupted, specifically the output of hormones T3 and T4 , it affects the life cycle of each strand of hair. This includes the development of hair at the root, how long it grows before falling out, and its replacement by new growth.

How Common Is It To Experience Hair Loss From Thyroid Medication

It’s fairly common to see some hair loss due to thyroid medication. Usually, this is due to overmedication, which leads to hyperthyroidism, because hair loss is a symptom of both low and high levels of thyroid hormone. In most people, this is a short-lived side effect that occurs in the first month of treatment.

Optimize Your Diet For Thyroid Health

The next step in reversing your thyroid hair loss is making sure your diet has been optimized for thyroid health, which includes ditching toxic and inflammatory foods and adding in plenty of the nutrients needed for essential thyroid function. So many of my patients have seen an improvement in their thyroid test results after going gluten-free I cover the scientific research behind the gluten-hormone connection in my book. Dairy is another big culprit for thyroid patients suffering from thyroid hair loss because of its chemical similarities to gluten and because it is so inflammatory for many people. Other inflammatory foods I recommend eliminating while you work to resolve thyroid hair loss include corn, soy, nightshades, eggs, nuts, and seeds.

Instead, youll want to focus on eating real, whole foods rich in the nutrients needed for thyroid health, including iodine, selenium, zinc, iron, vitamin D, B vitamins, and vitamin A. If you are low in these nutrients, your thyroid cant adequately produce its hormones, convert T4 to T3, or get T3 into your cells to attach to thyroid receptors, which can cause hypothyroidism symptoms, such as thyroid hair loss. I recommend a diet with plenty of grass-fed, pasture-raised meat, leafy greens, starchy vegetables, organic fruits, and healthy fats to combat thyroid hair loss. If you need some inspiration, my website has a ton of free recipes packed with nutrient-rich foods that make healthy living deliciously easy.

If I Stop Taking Synthroid Abruptly Will I Have Withdrawal Symptoms

Synthroid Side Effects EXPLAINED (Including Hair Loss, Weight Gain, Depression & More)

Stopping Synthroid wont make you have withdrawal symptoms.

But stopping Synthroid may cause you to have symptoms of the condition you were taking the drug to treat.

For example, if youre taking Synthroid for hypothyroidism, and you stop taking it, you may develop symptoms of hypothyroidism. This is because your symptoms were relieved when your body was getting thyroid hormone from Synthroid. But when you stop the drug, your body wont be receiving the hormone.

If you have questions about stopping treatment with Synthroid, talk with your doctor.

Your Thyroid May Be Causing Your Hair Loss: Heres How

If youâre seeing more hair than ever before stuck in the drain or your hairbrush, you may begin to worry that youâre losing your hair. Hypothyroidism is a fairly common cause of hair loss, and hypothyroidism-related hair loss can also be reversible.

âA blood test to rule out thyroid abnormalities should always be a part of the diagnosis for hair loss due to medical conditions,â Abraham Armani, MD, a hair-restoration surgeon and hair loss specialist in Dallas, Texas, tells WebMD Connect to Care.

According to the American Academy of Dermatology, it is normal to lose 50 to 100 strands of hair per day. If your hair is thick or long, a few dozen strands might look like a large clump, even if the number of hairs youâre losing is completely normal. But what if you are losing your hair?

If you follow the appropriate habits regularly, you can improve the health of your hair and body.

Yes Levothyroxine Can Cause Hair Loss

Hair loss can be one of the most frustrating symptoms associated with thyroid problems.

And thyroid-related hair loss is not just associated with low thyroid conditions but also high thyroid conditions as well.

Today, though, we will be focusing on hair loss associated with levothyroxine.

Levothyroxine is the most commonly prescribed thyroid medication out there right now.

In fact, its one of the most commonly prescribed medications in the United States.

Levothyroxine is used to treat patients who have LOW thyroid function so people who are taking this medication have hypothyroidism.

Levothyroxine is supposed to normalize thyroid function by providing your body with the very thing it needs if you dont have enough thyroid hormone.

We know that one of the side effects of having LOW thyroid function is hair loss.

And with that in mind, we have a little bit of a problem:

Taking Too Much Synthroid: Interindivdiual Variation In Dosing

Individuals undergoing treatment for hypothyroidism with synthroid are prescribed dosages aimed to optimize TSH levels. Excessively high TSH levels signifies that an individual is likely not getting enough synthroid. Since the severity of hypothyroidism is subject to individual variation and synthroid dosages necessitate patient-specific optimization, too much synthroid for one user may be a normal dose for another.

A person with severe hypothyroidism who weighs 200 lbs may take around 1.7 mcg/kg/day for a daily total dosage of ~154.22 mcg. Should the individual end up taking 175 mcg per day, he/she may exhibit subtle symptoms associated with too much synthroid. On the other hand, someone who weighs 140 lbs and is taking 1 mcg/kg/day for subclinical hypothyroidism, a total daily dosage may be just 63.5 mcg.

If the individual instructed to take 63.5 mcg of synthroid ends up taking 175 mcg per day, more severe symptoms are likely to emerge because the recommended dosage will have been surpassed by a significant amount. The lesser the extent to which an optimally calibrated dosage is surpassed, the less severe and/or numerous the symptoms of too much synthroid are likely to be. The greater the dosage over the optimal amount of synthroid needed for optimal function, the greater the symptomatic severity associated with the overdose.

Diagnosing The Cause Of Hair Loss

As a first diagnostic step, your vet will do a thorough physical exam, focusing on the skin and coat and looking for evidence of pain or any fleas.

Your vet will also ask about any other symptoms you might be seeing, like any scratching, head shaking, behavioral changes, vomiting, constipation, diarrhea, or urinary issues.

Mites, bacteria, yeast, and fungi like ringworm, can only be seen with a microscope so your vet will probably recommend checking for these with testing like skin scrapes, cytology, and fungal cultures.

Allergy testing can be done with a blood test or a skin test. Your vet may recommend blood and urine tests as well. Some unusual cases may need additional testing like a skin biopsy or may be referred to a specialist veterinary dermatologist.

How To Grow Your Hair Back

Okay, so let’s get into the specifics.

I mentioned previously that it can be difficult to figure out what is actually causing your hair loss and that’s because there are several things that matter to thyroid patients and no one else.

Let’s get into each of those:

#1. Thyroid hormone status.

The first and most obvious source of hair loss stems from the status of thyroid hormone in your body.

For most people, this will mean that you are NOT getting enough thyroid hormone.

If you don’t get enough then the hair in your hair follicles won’t grow, it’s quite simple.

This is also true for people who are taking thyroid medication.

The key to fixing this problem is to simply adjust your dose .

Taking a higher dose of thyroid medication will increase thyroid hormone status and improve hair growth.

You should also be aware that an excessively HIGH dose of thyroid hormone can also cause hair loss as well.

This is unusual, but it does happen from time to time.

Both a hyperthyroid and a hypothyroid state, induced by thyroid medication, can trigger hair loss.

But as I mentioned, probably 98% of you reading this are not taking enough thyroid medication so you will need to increase your dose.

#2. Thyroid medications.

The next source of hair loss can stem from the very medication that you are taking to try and fix thyroid hormone status.

That’s right! Thyroid medication ITSELF can cause hair loss regardless of the dose that you are taking.

There’s a big difference between those two.


Synthroid And Birth Control

Hair Loss

In most cases, youll continue to take Synthroid during pregnancy if you were using the drug before becoming pregnant.

However, if youre sexually active and you or your partner can become pregnant, its still important to talk with your doctor about your birth control needs. Theyll recommend whether you need to use birth control while youre taking Synthroid.

Its important to note that Synthroid may interact with certain birth control drugs. For more information about birth control drugs that may interact with Synthroid, see the Synthroid interactions section above.

What Does Thyroid Hair Loss Look Like

Thyroid hair loss often looks like a general thinning across your scalp or eyebrows. Thyroid hair loss might develop slowly patients with hypothyroidism or hyperthyroidism notice a gradual thinning of their hair rather than localized bald spots or missing patches. If youre brushing through your hair and notice chunks of hair leaving with each stroke, it might be time to get tested for a thyroid condition.

How To Slow Or Reverse Hair Loss

The best way to restore your hair is to treat underlying conditions like hypothyroidism. Although it can be hard to wait, be patient with your body as it learns to adjust to your thyroid medication.

Aside from medication, there are several other steps you can take to boost hair thickness and growth.

Eat a well-balanced diet

Hair requires plenty of nutrients that are abundant in wholesome foods like vegetables, fruits, and meat. To increase the rate your hair grows and for more density, eat foods with plenty of iron, keratin, zinc, and vitamins A, B, C, D, and E.

If you try a supplement to boost your nutrient intake, you may wish to look for one with biotin. Bear in mind that biotin can interfere with some thyroid lab results, so check with your lab to ask if you should avoid taking biotin before testing your thyroid.

Note: Paloma Health’s lab uses a specialized assay, so there is no need to delay your medications or supplements, including biotin. You may also take the Paloma Health at-home thyroid test with or without regard to food, so no need to fast.

Limit harsh styling practices

Coloring, permanents, and hot styling tools are some of the most harmful things you can do for your hair. However, many of us use these practices to get the look we want. If you style your hair with anything that may cause damage, try to limit it as much as possible.
